  • viscosity issue adding extra waxes?

    Posted by joseg on January 7, 2014 at 7:04 pm

    I have the following formula….without any thickener, initial aesthetics is like that of a regular cream, after 24 hours becomes a thick cream.
    (Formula A) Water, glycerin, stearyl alcohol, cetearyl alcohol, stearic acid, shea butter, coconut oil, sunflower oil, capric caprylic triglycerides, isopropyl myristate, emulsifiers, fragrance and preservative
    Now that I need a much thicker version, like a body butter, I decided to increase the waxes, add beeswax, cetyl esters and xanthan gum (Formula B)
    My issue is that Formula B is a flowing lotion, when I was expecting a thicker product. I’ve made the same thing without the gum and replacing emulsifiers but I’m still having the same issue.
    What am I missing here? Thanks.

    I would have increased oils, cetearyl and stearyl alcohol… (I don’t like using xanthan gum in cream)

    If you already have a thick formula A and want it to look like a butter in B. Don’t increase anything, specially capric capryic triglycerides and isopropyl myristate.

    Add just beeswax instead of increasing the rest.
    The best solution would be adding Structure CEL 500. Whenever I tested it I obtained a butter-like product.

    Thanks! I followed your advice and now I have a thick butter. I didn’t use Structure CEL because I need all natural ingredients in my formula though.
    I’m wondering you were suggesting me to watch out specially for capric capryic triglycerides and isopropyl myristate?

    If you were to add the triglycerides and isopropyl myristate, you would be negating the thickening effect of the extra waxes.
